Hi! I am a forum facilitator. Feel free to reach out if you have any questions.
Hi! For number 1: To delete a comment, simply click the three dots on the upper right side of the comment box, and you'll see an option to delete.
If you still can't see that option, please send us a screenshot of the options you see, and we'll have our tech team investigate further. Hope this helps!
Fixed. Thanks for flagging this!
